At first, Qin was one of the five generals of Shi Biao. Although Shi Biao has such a valiant soldier as Qin, Shi Biao himself is full of domineering and vanity. Qin soon saw that this was not something a monarch entrusted for life. So he defected, and Qin stayed for a while. He admitted that he was also the monarch of the worthy corporal, which made Qin loyal to him, so that he gave up the opportunity to turn over after the Xuanwumen rebellion.
Later, he followed Li Shimin, king of Qin, to all directions. Li Shimin is a man who knows people well and does his duty well. He attaches great importance to Qin Baoshu. He fought under his men, and Qin met Bole like a good horse, and made great achievements. It can be said that without Qin, the establishment of the Tang Dynasty would not be so smooth. However, when the 24 heroes of Lingyange were excluded, Qin was ranked at the bottom of the 24 heroes. The reason is also very simple, that is, Qin chose silence in the change of Xuanwu Gate.
Qin is a clever man. At that time, in the chaotic situation, only by maintaining a neutral position could he save his life. Otherwise, being too prominent will put yourself in danger.
